If you bought Allbirds stock last week for under $3, you might want to sit down.

On Wednesday, shares of BIRD — yes, the cozy sneaker brand your eco-conscious friend wouldn’t stop talking about — rocketed nearly 600%, touching as high as $23 per share before settling around $17 by end of day. The company’s market cap, which was a humble $21.7 million on Tuesday, ballooned to $159 million overnight. Not bad for a shoe brand that was practically being left for dead on the shelves.

So what happened? Allbirds announced it is completely walking away from footwear and rebranding itself as an artificial intelligence infrastructure company under the new name NewBird AI. The company also plans to raise $50 million, with the fundraise expected to close in the second quarter of 2026.

The pivot didn’t come out of nowhere. Just weeks earlier, in late March, Allbirds quietly sold off its entire footwear business — including the beloved Wool Runner — to American Exchange Group, the company behind brands like Aerosoles and Ed Hardy, for $39 million. Just like that, a decade of sustainable sneaker identity was gone.

Founded roughly ten years ago and taken public in 2021, Allbirds had spent years trying to hold its ground against rising competition. Shoppers increasingly abandoned the brand in favor of Hoka — sold under Deckers Outdoor Corporation (DECK) — and the Swiss performance brand On Running (ONON), both of which became cultural phenomena in the running and lifestyle shoe space. Investors lost patience, and the stock reflected it.

Now, NewBird AI wants to plant its flag in one of the most contested and lucrative spaces in tech today: AI compute infrastructure. The company says it plans to “acquire high-performance, low-latency AI compute hardware” and lease it out to businesses that simply cannot get their hands on enough chips through traditional channels.

And their reasoning is hard to argue with.

“The rise of AI development and adoption has created unprecedented structural demand for specialized, high-performance compute that the market is struggling to meet,” the company said in its press release.

They went further, pointing to a supply crunch that has been quietly squeezing the industry: GPU procurement lead times are stretching out, North American data center vacancy rates have hit historic lows, and virtually all compute capacity expected to come online through mid-2026 is already spoken for. The result, as NewBird AI describes it, is that “enterprises, AI developers, and research organizations are unable to secure the compute resources they need to build, train and run AI at scale.”

In plain terms — the world needs more AI horsepower, and nobody has enough of it. NewBird AI is betting it can step in and fill that gap.

Whether a former shoe company can credibly compete in the cutthroat world of AI infrastructure — alongside giants and well-funded challengers — remains the real question. But if Wednesday’s stock reaction is any indication, the market is at least willing to give the new bird its wings.
